Welcome! I would get an xpen and keep them confined with the pee pads, food, water and their beds if you can't watch them 100% of the time. WHen you can watch them I would still limit the space they have, maybe babygate your living room so you can reach them fast if they start to have an accident. You need to catch them actually going to punish them with a bad dog only. No hitting with anything. Then move them to the pad and say go potty. Also take them to the pad every two hours and stay with them til they go. Then give a treat and lots of kisses. There are tons of posts about housebreaking just do a search and you will find all kinds of great suggestions.
(also when you move to your new home put a clear plastic shower curtain under your xpen this will help with clean up) Good luck!!
